DESCRIPTION

This utility procedure determines whether a string matches a given
pattern. If it does, then Tcl_StringMatch returns 1. Otherwise
Tcl_StringMatch returns 0. The algorithm used for matching is the same
algorithm used in the stringmatch Tcl command and is similar to the
algorithm used by the C-shell for file name matching; see the Tcl
manual entry for details.
In Tcl_StringCaseMatch, the algorithm is the same, but you have the
option to make the matching case-insensitive. If you choose this (by
passing TCL_MATCH_NOCASE), then the string and pattern are essentially
matched in the lower case.
